The issue has taken time to resolve, but the solution is clever. Previously the VTEC equipped VFR ran on two valves per cylinder below 6800rpm, and four above. Now the motor switches to four valves at 6600rpm and back to two at 6100. Mechanically the system is identical to old (an oil pressure actuated pin moves into a chamber above the valve stem to engage the valve, and moves out to disengage), but the really clever stuff is electronic.
